About this calculator
The Car Loan Calculator helps you simulate vehicle financing, considering the total price, down payment, and term. It estimates the monthly installment amount and total cost of credit, making financial planning easier before closing a deal.
The calculation uses the constant payment formula (PMT), which considers the financed amount (car price minus down payment), the monthly interest rate, and the number of installments. The result shows each installment value and the total amount paid at the end of the contract.
This tool is useful for those buying a new or used car and wanting to compare different financing scenarios. For instance, you can test how increasing the down payment reduces installments or how longer terms lower monthly payments but increase total interest.
Important precautions: remember that the interest rate may vary according to your credit profile and the financial institution. Also, the calculation does not include insurance, administrative fees, or IOF, which can affect the final amount. Always check the APR before contracting.
Frequently asked questions
What is the difference between interest rate and APR?
The interest rate is the percentage charged on the financed amount. The APR (Annual Percentage Rate) includes interest, fees, insurance, and IOF, representing the true cost of the loan.
Can I use the calculator for a used car loan?
Yes, as long as you enter the total vehicle price, down payment, and desired term. The interest rate may differ for used cars, so adjust accordingly.
Does the calculator consider the down payment?
Yes, you enter the down payment amount, which is subtracted from the total price to calculate the financed amount. A larger down payment reduces monthly installments.
Does the result include insurance or additional fees?
No, the calculation only considers the financed amount and interest. For a complete budget, check the APR provided by the financial institution.
How can I simulate different terms?
Simply change the term field (in months) in the calculator. You will see the impact on the installment amount and total interest paid.
